Walls for Furnaces; and I do declare-the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art toswhich'it appertains' to make and use the same.

My invention relates in general to'an air for feeding air or other fluid to; the rear of the fire to increase combustion in the fire box and lessen the tardy combustion and generation of heat formerly'taking place in the. smoke stack. For wallsjoffthis character, a" horizontal plate anda preferably vertical back plate are employed to supportv the wall sections in the required manner, 'a nd it has been found that a one piece back'plate is subject to great warpingfrom the heat, Furthermore, ithasbeen extremely ar-duou's to install such a' one' piece device, due to its weight'and the cramped quarters in which the work must be done.

One object of my invention is to-con'struct both the horizontal and vertical plates of a plurality of sections which may easily bev handled and installemaand at the same time to so connect the sections as to reduce the liability of warping the back plate.

A further object is to provide a connecting means for the sections of the back plate which will assist in anchoring the Wallsections and which will be held wei ht of the latter.

et another ob ect is the provision of a novel arrangement, for mounting and-bracin place by the in the horizontal wall supporting plate.

ith theforegoing objects in view, the invention resides in the novel features of construction and unique association of parts hereinafter fully described and claimed, and

sections. t

tion of the present invention.

Fig. 18 is a detail section similar to a portion of Fig.1? but showing a still furtherform of support for theplate upon which the wall is mounted.

In F igures. 1 to 14 of the drawings above briefly described, "the numeral 1 designates the back of. the furnace of a water tube boiler, the inner side of said back-being provided with a wall 2 of fire-brick and clay. or

the like resting upon a channel iron beam or I other suitable support 3,v which beam is braced as seen at 4. All of this construction is common and well known and is merely illustrated to disclose A horizontal supporting plate 5 is provided for the air supply wall, said plate being formed of a plurality of elongated sections 6 abutting at their ends as seen at the applica- 7 in Figure 1, the rear edge of each section 6 being provided with a depending vertical flange 8 and with a plurality of rearwardly p s to returnto theair supplywall. The upper.

extending lugs 9 which are preferably cast on said flange. The lugs 9 are inset lnthe lower endof the wall 2, by chipping the tioned horizontally and with a vertical latter away suflicie'ntly and said lugs rest upon the beam 3 to support the greater part of the weight of the plate sections, saidsec tions being secured n place by means of bolts 10 passing throu h the flenges8- and 5 through the adjacent ange of said beam, llt'often happens that the beam '3 is of more or less irregular formation, and in order that the plate sections '6 maybe securely fastened to the same nevertheless, it IS highly desirable to provide the rear. side of the flanges 8 with vertical ribs 11 (see more particularly Figs; 2, 6, 7 and 8). These ribs are adapted to be chipped away-by a cold chisel or the likewhen the late sections 6 are installed and thus any irregularities in the beam 3 may be compensated for by removing more or less of the ribs where re uired.

etween their edges, the sections 6 are provided with elongated openings 12 adapted to supply air to the sectional wall yet to be described, and at their front edges of said sections turn downwardly or are otherwise suitably shaped at 13 toisupport. the

rear end of the grate 14. Suitable braces: 15 are secured at 16 to the furnace back 1 and the upper ends of these braces fit snugly in the angle between the-horizontal portions of the plate sections 6 and the down-turned edges 13 thereof, thus relieving strain fromv the bolts 17 which are employed to anchor the upper ends of said braces. The abutting ends of the plate sections 6 are provided with depending flanges 18 and the bolts 17 pass through these flanges and through the braces 15. Each of these braces is of the adjacent flanges 18 and received in notches 18 in said flanges to assist in supporting the weightof the-connected ends of the late sections. In addition to the connection between the plate sections aflorded their ends and each of said sections is provided along its lower edge with a lateral flange 24 adapted to be secured by bolts 25 to the plate 5, the intermediate portionsvof said sections having a plurality of longitudinal slots 26 to decrease weight and permit expansion and contraction of the plate sections without warping and consequently rovided' with a lateral shoulder 19 underlying both mamas edges of the sections 22 are each provlded witha. forwardly extending flange 27 posiflange'28 rising from the front edge of. the

flange 27, said flange 27 being provided with spaced sockets 29 for a purpose to appear.' .75, "form. of a fiat plate having slots 30 for the;

Each of the upper'sections 23 is n the same purpose as the slots 26, the upper.- portion of each section having a rib 31 on"; its rear side mset in a groove which is chipped in the wall 2, whereby to form" an,

air seal, while" the lower edge of each sec-w the lower sections22form a seat forthe 'tionis provided with a forwardly extending horizontal flange 32 having depending studs f 33 cast thereon. 'The'flanges 27 and 28 of studs 33 are receivedin the 'socketss29 to. I

prevent any great amount of shifting be-' tween the upper and lower sections, while permitting slight loose movement thereofunder changes in temperature. The m annerin which the upper and lower sections of the plate 21 engage ea'chother'is best illustrated in Fig.

' The air supply wall is composed of a plu-j 'ralitv of substantially flat vertical sections 34 which are shown applied in Figs. 1 and 2 and are detailedin Figs. 3, 4 and 5. Each section 34 is provided in its rear edge with a 'a notch 36 and at the upper end of said notch with a hook-37, the notch receiving the flanges 27 and 28 while the hook passes over i the latter and rests immediately above the flange 32. By this arrangement, it will be 'seen that the flange 28 and the hooks 37 will anchor the sections 34 until they are first shifted upwardly, and in addition itmay be pointed out that the weight, of the sections 34will retain the studs 33 properly received in the sockets 29, dueto'the disposition of the hooks 37. The weight of the fire bed resting on the wall also assists in this operation. by the bolts 17 additional bolts 20 are pref- The sides of the sections '34 are provided with shallow recesses '38 and with .ribs 39,

the latter being located along the'front edge portions of the sections and having notches 40 of various lengths and disposition to supply air from the recesses 38 just above the fire bed, the notches beingof the requisite size and location to produce the best results.

The air rises through the openings 12 into alongitudinal channel formed in the wall by registering notches 41 in the lower ends of the sections 34, and in order to guide such air through the notches 40 and at the same time to carry heat away from the ribs 39, other ribs 42 extend inwardly from said ribs 39 as shown clearly in Figs. 2, 3 and4. The

ribs 39 may be located to the best advantage 6?."similar to, the sections fiabove 5,; th erangement} iiiuaaea iai past the-wall 34 is'formed ofabuttingi b d escri e but the vertical flanges 8? of the sections Li" areprovided with no lugs'9' or ribs 11. T1118 armor the device isintended to be secured by .bolts 10 to a furnace 1 walll,2",' which is constructed entirely to the iloorvofthe fur-" nace from fire-brick, fire-clay orthe like, the

bolts 10 being passedentirely through the wall and through the flange Q8 as shown, clearly in Fig. 17. The end flanges 18 of the r; sections 6" are provided in their loweredges with notches 18 receiving-projecting lugs}; 19", said lugs being formedjon substantially ,horizontal flanges .15 on the upper ends of suitable pedestals or brace's 15?.,which per;

form'substantially the same functions as the braces 15, that is, supporting a great part of theweight resting V ,p I v plate of the wall 349, he pedestals 15? are vertically disposed and rest upon the bot tom of the furnace. and their upperends are secured by bolts 20 to the flanges 18% 7 Whenconverting thei'furnace for the use of oil, thismay be quickly and easily done by removing the sections of the air supply wall lifting the upper sections of theback plate 21 from the lower sections thereof, rcmoving the grate, and withdrawing the bolts 10 and 20 Also the air supplyjwall. and

its supporting means may be reinstalled with" In Fig. 18 a section emf; a. wall-supporting plate is shown, this section being'identical with the sections 6? above referred to with the exception that its end flanges 18 are. provided with two or more notches18 in their lower edges. These notches receive the upper edges of transverse bars 19 which extend entirely across the furnace and are supportedat their ends in suitable brackets 19 secured to the sides of the furnace. This method of upholding the supporting plate of the air supply-wall may in some instances be preferable and it also will permit quick and easy installation tire device. 1

The features not specifically described in connection with Figures 15, 16, 17 and 18, are identical with the corresponding parts of the first described form of the invention and need-not therefore be entered into in detail. 4

From the foregoing, taken in connection with the'accompanying drawings, it will beobvious that I have provided a simple arrangement of parts for carrying out the objects of the invention and sinceprobably the best results are obtained from the 'construc tion and arrangement disclosed, it is preferably'followed.
